All about GM

On May 1, General Motors released its 2023 Sustainability Report, showcasing the company’s commitment to building an equitable zero-emissions future and working toward its carbon-neutral goal. 

The report highlights GM's initiatives to accelerate EV adoption, forge partnerships to enhance supply chain sustainability, and support the development of a future-ready grid powered by renewable energy.

“We’re going to expand our reach, especially with many important EV launches across a wide range of price points and segments this year” said GM CEO Mary Barra.

The report provides a comprehensive look into GM's initiatives across key areas including environmental stewardship, innovation, social responsibility and governance through activities such as joining the ZEROgrid Initiative, expanding GM’s commitment to the First Movers Coalition to be inclusive of steel, aluminum, concrete and cement, and providing USD 64 million in grants to nearly 400 U.S.-based nonprofits to create inclusive solutions to social issues.

"We continue to make progress integrating sustainability into our business from the initial design and selection of materials, through product development and manufacturing, to innovative solutions for end of life” said Kristen Siemen, GM chief sustainability officer.

On April 26, GM Colombia announced the transformation of its business in Ecuador and Colombia, focusing on marketing and after-sales services, which implies the closure of plants in both countries, decided by GM International and GM South America.

The start of disassembly of the Colombia plant began on April 26 with a reduced team, while the OBB plant in Ecuador will continue working until the end of August 2024, when its production will cease.

These measures have been taken due to the fragmentation of markets and the underutilization of facilities since the Colombia plant operated at 9% while the Ecuador plant operated at 13%.

The company acknowledges the impact this decision will have on the affected employees, and will support them throughout their transition.
