  • “With the growth in both regulated and voluntary carbon markets and a renewed focus on international discussions/Article 6 in 2021, it is vital to keep up to date with the latest policy thinking and discussions. IETA and its staff provide valuable policy insights and also offers a unique forum to engage with other businesses involved in carbon markets.”

  • “We joined IETA because it’s the leading forum for ideas, discussion and action on the future of the carbon markets, and we’re keen to participate. We also want to keep abreast of major industry developments, and of course, spread the word about our efforts to bring transparency and quality to the markets. We’ve valued the opportunity to contribute to IETA’s consultation responses and the nuanced conversations with other members about current policy and market events. We look forward to continuing to work together with members in our quest to leverage data to win the battle against the climate crisis.
