The Cost Of Carbon Credits And How They Can Fight Climate Change
The European Commission has proposed an EU climate target for 2040 that allows countries to count carbon credits bought from developing nations towards the EU goal for the first time.
Here's what that means, and why the EU move on Wednesday faced criticism from campaigners and some scientists.
What Are Carbon Credits?
Carbon credits, or offsets, involve funding projects that reduce CO2 emissions abroad in place of cuts to your own greenhouse gas emissions.
Examples include forest restoration in Brazil, or converting a city's petrol buses to electric. The buyer counts "credits" for those emission reductions towards its climate goal, and the seller gets finance for their green project.
Proponents say the system generates much-needed funding for CO2-cutting efforts in developing nations and lets countries work together to cut emissions around the world.
However, the reputation of CO2 credits has been dented by a string of scandals in which credit-generating projects failed to deliver the climate benefits they claimed.
Why Is The EU Buying Them?
The European Commission proposed allowing up to 3 percentage points of the EU's 2040 target - to cut net emissions by 90% from 1990 levels - to be covered by carbon credits bought from other countries.
The EU's existing climate targets require countries to meet the goals entirely by cutting emissions at home.
The bloc's executive Commission said last year it hoped the EU could agree a 90% emissions-cutting target for 2040, with no mention of carbon credits.
Tumultuous geopolitics and the economic challenges of European industries have since stoked political pushback, with governments from Germany to Poland demanding a softer target.
In response, the Commission said it would add flexibilities, and landed on carbon credits as a way to retain a 90% emissions-cutting goal while reducing the domestic steps needed to reach it.
EU countries and the European Parliament must negotiate and approve the goal.
What Are The Risks?
The EU plan was welcomed by countries including Germany, which had pushed to include carbon credits in the goal, and by carbon credit project developers as a boost for climate finance.
But environmental campaigners said the EU was shirking domestic CO2-cutting efforts and warned against relying on cheap, low-value credits.
The EU's climate science advisers had also opposed buying credits under the 2040 target, which they said would divert money from investments in local clean industries.
The EU banned international credits from its own carbon market after a flood of cheap credits with weak environmental benefits contributed to a carbon price crash.
To try to address the risks, the Commission said it would buy credits in line with a global market and rules for trading carbon credits which the U.N. is developing. These include quality standards aimed at avoiding the problems that unregulated credit trading has faced in recent years.
Brussels will also propose rules next year on specific quality standards for the carbon credits the EU buys.
How Much Will It Cost?
The EU doesn't yet know. Carbon credit prices today can be as low as a few dollars per tonne of CO2, up to more than $100, depending on the project.
EU emissions records suggest the bloc would need to buy at least 140 million tonnes of CO2 emissions to cover 3% of the 2040 target, roughly equivalent to the Netherlands' total emissions last year.
One senior Commission official said the bloc was determined not to hoover up cheap junk credits.
"I don't think that would have any additional value. The credits we see currently on voluntary carbon markets are very, very cheap, and that probably reflects a lack of high environmental integrity," the senior official said.

Ensure fair prices for mangoes: CM N Chandrababu Naidu
TIRUPATI: Chief Minister N Chandrababu Naidu has urged mango farmers and pulp industries to work together to ensure fair prices for farmers, and sustained operation of processing units. He held an urgent review meeting with mango farmers, pulp industry representatives, and processing units of the erstwhile undivided Chittoor district on Thursday. Naidu directed the processing and pulp industries to immediately purchase mangoes from farmers to provide them relief. He assured that the government would also support the pulp and processing industries. He said the government would formulate a long-term plan to prevent future issues for mango farmers. Farmers brought to Naidu's attention that pulp industries were not purchasing mangoes, citing a lack of orders and storage space. Some farmers also reported that unloading itself was taking 3-4 days in certain areas. Responding to this, the Chief Minister instructed processing units and pulp industry representatives to immediately purchase the produce and support farmers. Mango pulp industries and exporters informed the Chief Minister that Pakistan and African countries have no import duties, while European countries impose high import duties. They urged Naidu to take up the matter with the Centre to persuade the European countries to reduce import duty. They also appealed for a reduction in GST on mango pulp from 12% to 5%. In response, the Chief Minister said he had already written to the Centre regarding the GST reduction, and would follow up on the matter again.

Will the EU delay enforcing its AI Act?
With less than a month to go before parts of the European Union's AI Act come into force, companies are calling for a pause in the provisions and getting support from some politicians. Groups representing big U.S. tech companies such as Google owner Alphabet and Facebook owner Meta, and European companies such as Mistral and ASML have urged the European Commission to delay the AI Act by years. The rules for general purpose AI (GPAI) models take effect on August 2, a Commission spokesperson reiterated, adding that the powers for enforcing those rules start only on August 2, 2026. Under the landmark act that was passed a year earlier after intense debate between EU countries, its provisions would come into effect in a staggered manner over several years. Some important provisions, including rules for foundation models like those made by Google, Mistral and OpenAI, will be subject to transparency requirements such as drawing up technical documentation, complying with EU copyright law and providing detailed summaries about the content used for algorithm training. The companies will also need to test for bias, toxicity, and robustness before launching. AI models classed as posing a systemic risk and high-impact GPAI will have to conduct model evaluations, assess and mitigate risks, conduct adversarial testing, report to the European Commission on serious incidents and provide information on their energy efficiency. For AI companies, the enforcement of the act means additional costs for compliance. And for ones that make AI models, the requirements are tougher. But companies are also unsure how to comply with the rules as there are no guidelines yet. The AI Code of Practice, a guidance document to help AI developers to comply with the act, missed its publication date of May 2. "To address the uncertainty this situation is creating, we urge the Commission to propose a two-year 'clock-stop' on the AI Act before key obligations enter into force," said an open letter published on Thursday by a group of 45 European companies. It also called for simplification of the new rules. A Commission spokesperson said the European AI Board is discussing the timing to implement the Code of Practice, with the end of 2025 being considered. Another concern is that the act may stifle innovation, particularly in Europe where companies have smaller compliance teams than their U.S. counterparts. While the Commission is set for GPAI rules to come in force from next month, its plan to publish key guidance to help thousands of companies to comply with the AI rules by year end would mark a six-month delay from its May deadline. EU tech chief Henna Virkkunen had earlier promised to publish the AI Code of Practice before next month. Some political leaders, such as Swedish Prime Minister Ulf Kristersson, have also called the AI rules "confusing" and asked the EU to pause the act. "A bold 'stop-the-clock' intervention is urgently needed to give AI developers and deployers legal certainty, as long as necessary standards remain unavailable or delayed," tech lobbying group CCIA Europe said.
