Climate action is increasingly a necessity that requires conversations and concrete actions to fight climate change. It requires more than commitments and declarations: it requires decisions, investment, knowledge and concrete actions capable of transforming our companies, cities and communities. During September and October 2026, two scenarios connected this global conversation with the challenges of the territories: Climate Week NYC, held in New York from September 20 to 27, and Climate Week Biodiversity 2026, which took place in Medellín between September 28 and October 10.
At TEVACORP we closely followed these agendas and were part of the Climate Week Medellín open agenda, a space that allowed us to recognize the role of organizations, citizens, academia and local initiatives in building solutions to climate change and biodiversity loss.
How can we transform the lessons learned and commitments of Climate Week into concrete actions and measurable climate outcomes from businesses, organizations, and our territories?
1. Climate Week NYC 2026: the time to turn commitments into action
Organized by Climate Group in coordination with the United Nations General Assembly, Climate Week NYC brought together business leaders, governments, social organizations, communities, investors and specialists to address major climate and economic challenges.

According to him Official report of Climate Week NYC 2026This year's edition brought together more than 1,500 events and more than 120,000 participants. Its central message was forceful: the economic argument in favor of climate action already exists; now it is necessary to accelerate its implementation.
The agenda addressed 12 key issues:

The need to accelerate the energy transition and strengthen electrical infrastructure was highlighted. A survey of nearly 2,000 business leaders in 18 countries revealed that 90% expected their companies to be mostly electrified by 2035. Furthermore, the growth of artificial intelligence and data centers reinforces the importance of integrating sustainability into investments, production processes and business planning.
2. From New York to Medellín: a global conversation that lands in the territory
Between September 28 and October 10, 2026, Medellín was the setting for Climate Week Biodiversity, an international platform that articulated climate action, biodiversity conservation and the search for territorial solutions. According to the Mayor's Office of MedellínThe event registered more than 13,200 registered people from 30 countries, with an agenda of more than 240 activities and nearly 150 confirmed speakers. The core programming ran from September 28 to October 1, while the open agenda extended conversations to academic, community, cultural and environmental spaces until October 10. Unlike the global emphasis on energy, electrification, and economic transformation that characterized much of the talk in New York, Medellín brought biodiversity, water, and solutions that can be implemented in cities and territories to the forefront. Its main thematic axes were:

The city thus offered an opportunity to connect major global challenges with decisions made in neighborhoods, businesses, educational institutions and communities.
3. TEVACORP as an ally of the open agenda #ClimateWeekMedellin2026
At TEVACORP we were part of the open agenda of #ClimateWeekMedellin2026 with two Workshops focused on decarbonization and the circular economy 2.0, recognizing the value of these spaces to connect knowledge, initiatives and actors that work for sustainability.

This participation connects with our purpose: to strengthen the link between people, nature, organizations and territories, promoting solutions that integrate environmental and social sustainability. The open agenda was especially important because it allowed the conversation to extend beyond the central scenarios and bring it closer to organizations, groups, institutions and citizens who also have a lot to contribute.
4. Colombia facing the climate challenge: from national goals to organizational management
In December 2025, Colombia updated its Nationally Determined Contribution (NDC 3.0), establishing climate commitments towards 2035 in mitigation, adaptation, biodiversity, environmental justice and just energy transition. This roadmap is linked to the goals of reducing greenhouse gas emissions by 51% by 2030 and achieving carbon neutrality by 2050. However, national commitments require decisions and progress from each economic sector and each territory. For companies and organizations, this means asking: Are we identifying our climate impacts and risks, ecosystem dependencies, and actions needed to integrate sustainability into our decisions?
5. Five actions to bring Climate Week to your organization

The talks in New York and Medellín can become concrete opportunities, with the understanding that it is not necessary to solve all challenges at the same time. The important thing is to start with clear priorities and move forward steadily, measuring results and adjusting actions when necessary.
6. Change is in everyone: let's build solutions from our territories
Climate Week 2026 leaves a common message: climate action needs to connect knowledge, financing, innovation, nature and social participation. At TEVACORP we believe that every company, institution, community and person can contribute to this transformation. To do this, we need to strengthen capacities, measure our impacts, recognize our responsibilities and build partnerships that move towards a more sustainable and resilient future.
Are your company and your team ready to move from commitment to climate action?
