Altesca is conscious about the investments we make and the projects we embark on. We seek to find opportunities that are proven to make a difference in our fight to save the world. We acknowledge the threat that climate change brings to our world and all good in it. We, for one, won’t stick to our old ways or invest just because it makes money. We only want to work on projects that make a difference.
