Sustainable engineering for climate change

As the adverse effects of climate change continue to wreak havoc on economies worldwide, the focus is shifting towards sustainable engineering solutions for climate change. Buildings collapsing and causing massive economic losses have underscored the urgency for nations to adopt sustainable practices. CNBC Africa recently interviewed the President of the Institution of Engineers of Kenya, Erick Ohaga, to discuss this pressing issue. The conversation centered around finding ways for infrastructures critical for economic development to coexist with the environment without causing harm. Ohaga highlighted the importance of exploring various solutions and embracing eco-design and resilient engineering. However, the elephant in the room remains the funding gap. Despite the commitment to green financing, securing adequate funds continues to pose a challenge. Ohaga emphasized the need for developing local content and leveraging public-private partnerships to bridge the funding gap. The institution is also eyeing partnerships to tap into green financing initiatives like COP27 pledges. Ohaga pointed out the success story of Ethiopia's dam project, funded by its people through bond issues, as a testament to Africa's capability to finance critical projects. With a vision to achieve a renewable and clean energy mix by 2030, Ohaga reiterated the importance of reducing greenhouse gas emissions while driving industrial growth. In response to the funding challenge, Ohaga advocated for local participation in financing infrastructure projects, signaling a shift towards a self-reliant and sustainable development model. The interview also delved into the role of nuclear and renewable energy in fostering a green economy. Ohaga highlighted the clean energy advantages of nuclear power plants, emphasizing their capacity to significantly reduce greenhouse gas emissions. While some African countries have embraced nuclear energy, concerns around safety persist. Ohaga reassured that the nuclear industry is highly regulated, with stringent safety, security, and policy frameworks. He compared the safety standards of nuclear plants to the aviation industry, citing their meticulous approach and minimal accident record. Ohaga underscored the importance of public trust in nuclear energy and dispelled myths around its safety. The conversation concluded with a call for political will to embrace sustainable engineering solutions, including nuclear energy, as a means to achieve a greener future in Africa.
